Key takeaway

📌 KEY POINTS ✅ Profitable ≠ cash-positive — a project can be profitable but cash-negative for months. ⚠️ Customer invoice date ≠ cash receipt date — payment terms and collection risk matter. 💡 Use actual open AP/AR positions, not assumed contractual dates. ━━━━━━━━━━━━━━━━━━━━ ▶ 1.

Explanation

📌 KEY POINTS
✅ Profitable ≠ cash-positive — a project can be profitable but cash-negative for months.
⚠️ Customer invoice date ≠ cash receipt date — payment terms and collection risk matter.
💡 Use actual open AP/AR positions, not assumed contractual dates.

━━━━━━━━━━━━━━━━━━━━
▶ 1. WHY THEY DIVERGE

Procurement payments often occur before customer billing
A project can be profitable but cash-negative for months as a result

━━━━━━━━━━━━━━━━━━━━
▶ 2. FORECAST INPUTS

Planned procurement/labor outflow timing
Open commitments
Invoice/payment terms
Expected customer billing dates — not the same as cash receipt

━━━━━━━━━━━━━━━━━━━━
▶ 3. WHY IT MATTERS EVEN WITHOUT REVENUE

Internal/capital projects: cash outflow planning aids treasury and funding decisions
Customer projects: compare cumulative inflow vs. outflow to find the peak funding requirement

━━━━━━━━━━━━━━━━━━━━
⚠️ 4. DATA DISCIPLINE

Use actual open AP/AR positions where available — don't assume contractual dates still hold
Refresh the forecast as supplier schedules and milestone billing change
Never manipulate cost planning to fake a cash forecast — cost, commitment, invoice, and payment are different time/value concepts

✅ CHECKPOINT: name the four cash-forecast inputs.

Real project scenario

A profitable engineering project required heavy equipment purchases six months before the first customer milestone invoice. Cash-flow forecasting identified a temporary funding requirement that margin reports did not show.

Common mistakes

Treating revenue as cash receipt.
Treating PO commitment as payment.
Using cost plan dates as payment dates without adjustment.
Ignoring payment terms.
Looking only at total project margin.

Best practices

Forecast invoice and payment timing separately.
Update from open AP/AR.
Include commitments.
Track peak funding requirement.
Keep margin and liquidity views separate.

Interview angle

Explain why project cash flow differs from project cost/revenue and what timing data is needed.
